Eclampsia, like pre-eclampsia, tends to occur more commonly in first pregnancies than subsequent pregnancies. [38] [39] [40] Women who have long term high blood pressure before becoming pregnant have a greater risk of pre-eclampsia. [38] [39] Patients who have gestational hypertension and pre-eclampsia have an increased risk of eclampsia. [41]
Pre-eclampsia affects 2–8% of pregnancies worldwide. [4] [17] [12] Hypertensive disorders of pregnancy (which include pre-eclampsia) are one of the most common causes of death due to pregnancy. [6] They resulted in 46,900 deaths in 2015. [7] Pre-eclampsia usually occurs after 32 weeks; however, if it occurs earlier it is associated with worse ...
Preeclampsia does not in general increase a woman's risk for developing chronic hypertension or other heart-related problems. Women with normal blood pressure who develop preeclampsia after the 20th week of their first pregnancy, short-term complications, including increased blood pressure, usually go away within about six weeks after delivery.

Menopause typically occurs between 44 and 58 years of age. [8] DNA testing is rarely carried out to confirm claims of maternity at advanced ages, but in one large study, among 12,549 African and Middle Eastern immigrant mothers, confirmed by DNA testing, only two mothers were found to be older than fifty; the oldest mother being 52.1 years at conception (and the youngest mother 10.7 years old).
Risk factors associated with the development of this complication include maternal age over 30 years, multi gestational pregnancy, family history of cardiomyopathy, previous diagnosis of cardiomyopathy, pre-eclampsia, hypertension, and African ancestry. The pathogenesis of peripartum cardiomyopathy is not yet known, however, it is suggested ...
HELLP syndrome occurs in about 0.7% of pregnancies and affects about 15% of women with eclampsia or severe pre-eclampsia. [5] [2] Death of the mother is uncommon (< 1%). [1] [3] Outcomes in the babies are generally related to how premature they are at birth. [1] The syndrome was first named in 1982 by American gynaecologist Louis Weinstein. [2]
The average age of a girl's first period is 12 to 13 (12.5 years in the United States, [6] 12.72 in Canada, [7] 12.9 in the UK [8]) but, in postmenarchal girls, about 80% of the cycles are anovulatory in the first year after menarche, which declines to 50% in the third year, and to 10% by the sixth.

According to a meta analysis from 2017 of 63 cohort studies and 12 case control studies, advanced maternal age(≥35 years) increased the risk of stillbirth (OR 1.75, 95%CI 1.62 to 1.89). It also increased the risk for FGR (fetal growth restriction) (OR 1.23; 95%CI 1.01–1.52). It is suggested that the rise in the risk could be due to ...
